Fig. 2 is a flowchart illustrating a VPN networking method according to an embodiment of the present application, where the method is applied to a site, and includes:
step 201: responding to the dialing request, and acquiring current VPN networking configuration information configured on a network side;
the method comprises the steps that a site sends a dialing request to a network side to request the network side to distribute a corresponding IP address for the site, the site accesses a VPN network by using the distributed IP address, when the site sends the dialing request, the site specifically needs to obtain current VPN networking configuration information configured by the network side, the current VPN networking configuration information comprises a server address, the site sends the dialing request carrying a user name and a password of dialing, and the site requests to establish connection with a corresponding server.
The current VPN networking configuration information related to the embodiment of the invention is VPN networking configuration information configured by a network side and is VPN networking configuration information used for the first time when a site dials currently.
The site triggers to generate a dialing request, which may be a dialing request actively triggered when a set condition is met, or a dialing request triggered according to the instruction of a user.
As an optional implementation manner, in response to the dialing request, the current VPN networking configuration information configured on the network side is obtained, which may be any of the following manners:
1) Responding to a dialing request triggered when a site is started, and acquiring current VPN networking configuration information configured on a network side;
when a station is started each time, a dialing request is sent to a network side, the dialing request carries a serial number SN of the station, and the network side receives the dialing request and then allocates a corresponding IP address for the station.
2) And acquiring the current VPN networking configuration information configured by the network side in response to a dialing request triggered after receiving the VPN networking configuration information issued by the network side.
The network side can configure and modify VPN networking configuration information for the site, the network side issues the VPN networking configuration information to the site after completing and modifying the configuration, and the site determines that the VPN networking configuration information is updated after receiving the VPN networking configuration information from the network side every time, triggers and generates a dialing request so as to dial by using the updated VPN networking configuration information.
the current VPN networking configuration information includes the address of the configured VPN server, dialing is performed by using the current VPN networking configuration information, and the process of requesting access to the corresponding VPN server is an existing process, which is not described in detail herein.
when the current VPN networking configuration information is used for dialing, if a corresponding VPN server is accessed in a preset time period, the dialing is considered to be successful, otherwise, the dialing is considered to be failed.
In the embodiment of the invention, when the current VPN networking configuration information is failed to dial, whether the backup VPN networking configuration information is stored locally or not is checked, and the backup VPN networking configuration information is the VPN networking configuration information stored when the last dialing is successful.
And if the backup VPN networking configuration information is stored, dialing by using the backup VPN networking configuration information and requesting to access a corresponding VPN server.
And 204, when the current VPN networking configuration information is used for dialing successfully, saving the current VPN networking configuration information as backup VPN networking configuration information.
When the current VPN networking configuration information is used for dialing successfully, the current VPN networking configuration information is used as backup VPN networking configuration information to be stored, and therefore, when the next dialing fails, the backup VPN networking configuration information can be used for dialing.
By using the VPN networking method provided by the embodiment of the invention, since the site local stores the VPN networking configuration information which is successfully dialed at the last time, if the VPN network is interrupted in the process of the related configuration of the VPN networking due to the instability of the internet of things or the wireless network, the related configuration of the new VPN networking is not modified and completed.
As an optional implementation manner, when dialing fails by using the current VPN networking configuration information and it is determined that backup VPN networking configuration information is not locally stored, acquiring stored default VPN networking configuration information; and dialing by using the default VPN networking configuration information, and requesting to access a corresponding VPN server.
For the situation that a site initially accesses a VPN network, if the site initially fails to dial by using current VPN networking configuration information, backup VPN networking configuration information is not locally stored in the site.
The default VPN networking configuration information is VPN networking configuration information preset in a site when the site leaves a factory, and the default VPN networking configuration information configures an address of a public VPN server, so that the site can be ensured to be correctly accessed to a VPN network.
As an optional implementation manner, when dialing fails by using the backup VPN networking configuration information, acquiring stored default VPN networking configuration information;
and dialing by using the default VPN networking configuration information to request to access a corresponding VPN server.
If the corresponding server modifies the matching relation with the site after the last dialing is successful, the dialing fails when the backup VPN networking configuration information is used for dialing, and in order to ensure that the site can be correctly accessed into a VPN network, the embodiment of the invention utilizes the default VPN networking configuration information for dialing at the moment and requests to access the corresponding VPN server.
As an optional implementation manner, when a site is initially started, because current VPN networking configuration information configured on a network side is not obtained, dialing may be performed by using default VPN networking configuration information to request access to a corresponding VPN server.
When the network side configures the VPN networking configuration information, in order to prevent the VPN networking configuration information from being wrong due to wrong input configuration information, so that a site cannot access a VPN network by using the current wrong VPN networking configuration information, the current/backup/default VPN networking configuration information in the embodiment of the invention comprises main VPN server configuration and backup VPN server configuration, and the current/backup/default VPN networking configuration information is used for dialing, and the method comprises the following steps:
dialing by utilizing the configuration of the main VPN server and requesting to access the corresponding main VPN server;
and when the dialing configuration by using the main VPN server fails, dialing is performed by using the backup VPN server configuration, and the access to a corresponding backup VPN server is requested.
As an optional implementation manner, after the site accesses the backup VPN server, it checks whether the site can access the primary VPN server;
and when the main VPN server is determined to be accessible, disconnecting the backup VPN server, and reusing the configuration of the main VPN server for dialing.
The embodiment of the invention realizes the VPN active-standby mechanism and enhances the usability of the VPN network. In some scenarios, if the backup VPN server is used to connect normally, it is further required to check whether the network of the primary VPN server is connected, and if the network of the primary VPN server is accessible, it is required to disconnect the current backup VPN server and try to establish a VPN connection with the primary VPN server.
Specifically, in the embodiment of the present invention, the current VPN networking configuration information includes an address of the first primary server and an address of the first backup server, and the dialing is performed by using the current VPN networking configuration information, where the dialing includes:
dialing by utilizing the configuration of the first main VPN server to request to access the corresponding first main VPN server;
and when the dialing configuration by using the first main VPN server fails, dialing is performed by using the configuration of the first backup VPN server, and the corresponding first backup VPN server is requested to be accessed.
As an optional implementation manner, since the backup VPN networking configuration information is VPN networking configuration information that has been dialed last time successfully, in the embodiment of the present invention, the backup VPN networking configuration information includes an address of the second master server and an address of the second backup server, and dialing is performed by using the backup VPN networking configuration information, including:
dialing by utilizing the configuration of the second main VPN server to request to access the corresponding second main VPN server;
and when the dialing configuration by using the second main VPN server fails, dialing is performed by using the configuration of the second backup VPN server, and the corresponding second backup VPN server is requested to be accessed.
Further, in the embodiment of the present invention, the default VPN networking configuration information includes an address of a third primary server and an address of a third backup server, and dialing is performed by using the default VPN networking configuration information, where the dialing includes:
dialing by utilizing the configuration of the third main VPN server to request to access the corresponding third main VPN server;
and when the dialing configuration by using the third main VPN server fails, dialing is performed by using the third backup VPN server configuration, and the corresponding third backup VPN server is requested to be accessed.
The embodiment of the invention modifies the VPN networking configuration information of the site, and only modifies the current VPN networking configuration information. Even if the VPN networking configuration information is wrongly modified, after the VPN dialing fails for a period of time, the backup VPN networking configuration information (if the backup VPN networking configuration information is locally stored) or the default VPN networking configuration information (if the backup VPN networking configuration information is not locally stored) which is originally and successfully dialed and stored can be used for connecting an original VPN server (after the new VPN server is deployed, the original VPN server needs to be removed after all equipment is migrated to the new VPN server).
As an optional implementation, the method further comprises: and triggering the site to restart when the dialing fails by utilizing the default VPN networking configuration information.
In the related art, due to instability of the internet of things or a wireless network, it is likely that an unattended site performs VPN redialing in a VPN networking related configuration process, for example, when a network side performs VPN networking related configuration on a site B, the site B releases an IP address, the site a performs redialing, and the site a uses the IP address released by the site B, the configuration of the site B is modified to the site a according to the existing manner.
The method for networking a VPN provided in the embodiment of the present invention further includes:
sending a configuration request to a network side, receiving VPN networking configuration information issued by the network side, and specifically uploading a program and a configuration file related to the VPN networking configuration information to a site by the network side;

and if the VPN configuration information is consistent with the VPN configuration information, updating the current VPN networking configuration information to VPN networking configuration information issued by the network side.
The SN code is a unique identification code of the station. When the program is transmitted to the site, if the VPN IP of the site is changed, the program can compare the incoming parameter (site SN code) with the site self-solidified SN code to determine whether the site is a target site, and if the site is not the target site, the program does not execute operation to prevent the site from mismatching.
